FOAMULAR
®
Insulating Sheathing
Extruded Polystyrene (XPS) Rigid Foam Insulation
Energy-Saving, Moisture-
Resistant XPS Insulation
Film-Faced Insulating Sheathing
for Damage Control
ASTM C578 Type X, 15 psi
minimum
Description
Used as sheathing over all
exterior walls in wood or
metal framing construction,
FOAMULAR
®
Insulating
Sheathing (IS) XPS Insulation
creates an effective insulating
envelope over the entire
structure.
FOAMULAR
®
(IS) XPS Insulation
is ideal for either wood or metal
framing construction, and suits a
variety of exterior nishes. These
strong, lightweight, rigid foam
panels with a lm face provide
the durability and damage
resistance necessary to meet the
rigorous demands of site built
construction. It is highly resistant
to moisture and retains its long
term R-value, year after year—
even after prolonged exposure to
moisture and freeze/thaw cycling.
Key Features
• Readily combines with blanket-
type insulation for greater
R-value
• Used in re-rated exterior wall
assemblies for application in
of ce buildings, schools,
shopping centers and more
• Tough lm facers for added
damage-resistance
• Excellent long-term stable
insulating performance with an
R-value
1
of R-3, R-4 or R-5
• Exceptional moisture resistance,
long-term durability
• Limited lifetime warranty
2
—
maintains 90% of R-value
and covers all ASTM C578
properties
• The only XPS foam to have
achieved GREENGUARD Gold
Certi cation
• The rst XPS foam with
certi ed recycled content—
certi ed by Scienti c
Certi cation Systems (SCS)
to contain a minimum 20%
recycled content
• Will not corrode, rot or
support mold growth
• Zero ozone depletion potential
with 70% less global warming
potential than our previous
formula
• Reusable and remnants from
manufacturing are recycled back
into new XPS Foam Insulation
• Lightweight, durable rigid
foam panels are easy to handle
and install
• Easy to saw, cut or score
Technical Information
This product is combustible. A
protective barrier or thermal
barrier is required as speci ed
in the appropriate building code.

All construction should be
evaluated for the necessity to
provide vapor retarders. See
current ASHRAE Handbook of
Fundamentals.
FOAMULAR
®
XPS Insulation
is a non-structural material and
must be installed on framing
which is independently braced
and structurally adequate to meet
required construction and service
loading conditions.
FOAMULAR
®
Insulation can be
exposed to the exterior during
normal construction cycles. During
that time some fading of color
may begin due to UV exposure,
and, if exposed for extended
periods of time, some degradation
or “dusting” of the polystyrene
surface may begin. It is best if the
product is covered within 60 days
to minimize degradation. Once
covered, the deterioration stops,
and damage is limited to the thin
top surface layers of cells. Cells
below are generally unharmed and
still useful insulation.
